the exponents represent how many times we should multiply the base by itself
OpenStudy (pphalke):
2*2*2*2*2*2*2

Nnesha (nnesha):
2^8 = multiply 2 by 2 (8 times)
\[2*2*2*2*2*2*2*2 \] is not same as 2^3
alones (alones):
Oh blah, i got it wrong it's \[\frac{ 1 }{ 8 }\]
Nnesha (nnesha):
then the question is \[2^{-3}\] ??
Nnesha (nnesha):
there is only reason you can flip the fraction (negative exponents)
\[\frac{2^{-3}}{1}= \frac{1}{2^3}\]
alones (alones):

Nnesha (nnesha):
by the way \[2^{-3}\] is same as \[\frac{ 2^{-3} }{ 1 }\]
and yes if the answer is 1/8 then the question should be 2 to the negative 3rd power
alones (alones):
Thanks, at first i kinda got confused
Nnesha (nnesha):
easy way to deal with negative exponents
change the place and sign
if the `negative exponent` is in the denominator move that to the numerator and change sign
